Types of rocks
Types of rocks
This report is expected to explain the formation, the imporatance and the caracteristics of the three more comoun types of rocks in the earth.
Igneous rock
Igneous rocks are formed by the solidification of magma (undergrownd melted rock), when magma emerge from the underground the temperature of this one get lower untill it solidificates. This type of rock are mostly found in oceans or near divergent movements of plates techtonics. The uses for igneous rocks are construction because of the durabilty and the strong or also there are many minerals extracted from this rock.
Sedimentary rock
The sedimentary rock is produced by the compactation and sementation of rocks which pices fall off or where erosioned by air, water, ice or gravity; thats way we can found them in the upper part of earth crust . They are mostly used for highway constructions, buildings, or even for chalks in schools.
Metamorphic rocks
Metamorphic are mostly found in montainous parts of the earth crust; they are produced by proces in wich de molecular structure of a rock change with the help of heat and preasure. Metamorphic rocks are mostly used for roof material, decorative stones (garden), building material and sculpture material.
As a conclusion we can see that rocks are more important than what we thought, if there where no rocks most of the things that we know now a days as buildings, highways,etc. Would not exist and this will bring lot’s of problems or changes

An essay of "the prision"
The story "The Prison" written by Bernard Malaud, is about a guy called Tommy Casteli, that stole a licorshop so his father arranged his marriage and his job in a candy store. This essay will analize the three simbols of the story, the candy store, the little girl and the tissue papers.
The first symbol is the candy store. The candy store symbolises Tommy's life, Tommy's imprisonment and how Tommy was not able of decide what his life was going to be. "Un endurably slow hours and endless drivel that went with seling candy, cigarets and soda".
The second symbol is the little girl. The little girl symbolises Tommy's past and through her he remembers the bad things she had done or his mistakes in life, the little girl also was a way of making Tommy's day more interesting "found himselfw thinking about that his life had turned out, and then about this girl, moved that she was so young and a thief"
The third and last symbol is the tissue papers that symbolise the little girl excuse to go to the store and through them she can steal "Tommy opened the drawer to get the girl her paper (...) but she saw a white hand reach into the candy case for a chocolate bar and for an other, then she came forth from behind the couter and stood there inocently waitin for him"
In this essay the symbols of the story "The prison" were analised. Thus is a great story in which the life of the main character is reflected in a little girl action; and it is very interesting to read.
